Approximately 13 per cent of Swedish women between the ages of 20 and 29 say that they have had a prolonged period of coital pain, something which prevents them from enjoying a normal sex life and which can seriously affect their relationships.
The majority of these women suffer from vulva vestibulitis, which is characterised by lasting penetrative pain and tenderness in the region around the vaginal opening (the vulvar vestibule). The researchers believe that the pain is caused by a combination of factors, both physical and mental, but the condition is poorly understood and there is no simple effective treatment.
Gynaecologist Ulrika Johannesson has now demonstrated in her doctoral thesis that contraceptive pills affect the body in ways that can increase the risk of pain. Healthy women who are on the Pill have lower pain thresholds on the area around the vaginal opening, a greater number of superficial blood vessels, and a different mucosa profile than healthy women who do not take oral contraceptives.
“These women are healthy and experience no pain during sexual intercourse,” says Dr Johannesson. “However, it is possible that changes in their mucosae make them less resistant to mechanical stress, and this can cause microfissures. We believe that this, in combination with the lower pain threshold, can contribute to vestibulitis.”
Dr Johannesson’s thesis confirms previous research showing that long-term use of contraceptive pills can increase the chances of developing vestibulitis. However, she stresses that there is no reason for women to go off the Pill if they are not experiencing pain during sexual intercourse.
“The Pill is an excellent form of contraceptive, but if you’re taking it and if you start getting problems with fissuring and pain, you should contact your doctor or your clinic; it’s a good idea to then go off the pill for a while to see if the problems go away,” she says.

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.
The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...
For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
